hallo, foamers, - Introduce of my case:
I'm doing a simulation of incompressible, turbulent flow, two outlets with different pressure, I use inletoutlet boundary condition.For solver i use simpleFoam. There is no problem of my mesh quality, checked by 'checkMesh'. If i close one outlet, it will converge well.
(Here in the attachments is my 'boundary conditions' 'fvScheme' and 'fvSolution'. and my result of calculate)Problem:
You can see that the 'Initial residual' increase after about '50' iterations. I have no idea about this..
I think it's the problem of settings in 'fvScheme', but i don't know how to deal with it, because i don't understand these schemes at all. If anyone can give me some suggestions...
Thanks very much for your help.resultat.txt
